Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for tobacco processing, and in particular to a tobacco loading elevator. Background Technology

[0002] After the tobacco leaves mature and are harvested, they need to be stalked and placed in curing barns for drying. This process usually requires manual labor, with farmers using ladders to place each stalk of tobacco onto the second or third tier of the barn. This process presents several problems: First, it is inefficient; for large-scale tobacco curing operations, manual loading is inefficient and cannot meet production demands. Second, it is physically demanding; workers need to repeatedly climb ladders or supports, operating at heights, resulting in extremely high work intensity and significant physical harm. Third, it presents numerous safety hazards; workers are prone to falls and other accidents due to fatigue or mistakes while working at heights. Especially during the tobacco loading season, the workload is heavy, and workers are in a state of high stress for extended periods, further increasing the safety risks.

[0003] In the prior art, such as the Chinese utility model patent with announcement number CN221104756U and announcement date of June 11, 2024, a tool for loading tobacco in a dense tobacco curing barn includes a vehicle body, a scissor lift mechanism, and a lifting platform. The lifting platform is connected to the vehicle body through the scissor lift mechanism. The vehicle body includes a main frame, a drive mechanism, and a direction control mechanism. The drive mechanism includes a drive wheel set, a power unit, and a transmission component. The power unit is connected to the drive wheel set through the transmission component. The direction control mechanism includes a directional wheel set, an L-shaped support, and omnidirectional wheels. The directional wheel set is mounted on the main frame, and the omnidirectional wheels are rotatably connected to the main frame through the L-shaped support. The scissor lift mechanism drives the lifting platform to move up and down, and the drive mechanism drives the lifting platform to move on the ground. When the scissor lift mechanism retracts, only the omnidirectional wheels are in contact with the ground, and the drive wheel set and the power unit are disengaged. When the scissor lift mechanism extends, both the omnidirectional wheels and the directional wheel set are in contact with the ground, and the drive wheel set and the power unit are reconnected. Although the patented method can achieve the application of tobacco to dense curing barns, it still requires workers to stand on the vehicle and hang the tobacco rods on the drying rack. This requires tilting the tobacco rods first and then vertically attaching them to the drying rack, which is difficult to operate and poses a high risk to workers.

[0004] Therefore, there is an urgent need for a smoke loading device that can automatically lift and lower, and is efficient and safe, to solve these problems. Utility Model Content
